Now this is a comparison that many bike lovers in India have been waiting for. In 2025, we’ve got three hot machines stealing the spotlight – the Bajaj Pulsar NS400Z, the sharp and track-focused KTM Duke 390, and the newly launched retro-styled Royal Enfield Guerrilla 450. Each of them has a distinct personality, and they all appeal to different types of riders. But which one is the real all-rounder for Indian roads?
Let’s have a fun and honest chat about how these bikes stack up when it comes to design, performance, comfort, mileage, features, pricing, and real-world value. Whether you’re upgrading from a 150cc bike or buying your first powerful machine, this comparison will help you make the right pick.
Bajaj Pulsar NS400Z vs KTM Duke 390 vs Royal Enfield Guerrilla 450 Design Comparison
Starting with looks, the Bajaj Pulsar NS400Z carries forward that muscular Pulsar DNA, but with a more aggressive tank design, sharp LED projector headlamp, and sporty graphics. It looks big and bold, almost like a naked streetfighter that doesn’t try too hard. The riding posture is sporty, but still manageable for city rides.
On the other side, the KTM Duke 390 looks razor-sharp. Its exposed frame, sleek panels, and compact body scream “track-ready”. It’s definitely the flashiest of the three. The Royal Enfield Guerrilla 450, meanwhile, plays the retro card. It has that classic round headlamp, metal tank, upright bars, and a no-nonsense vibe. If you want something timeless and solid, the Guerrilla has great road presence.
Bajaj Pulsar NS400Z vs KTM Duke 390 vs Royal Enfield Guerrilla 450 Performance Comparison
Performance-wise, all three bikes pack a serious punch but in different styles. The NS400Z uses the Dominar 400’s 373cc engine tuned for 40 PS. It feels strong on the highway and surprisingly smooth in city traffic. It’s not as aggressive as the KTM, but it’s super usable for everyday fun.
The KTM Duke 390, with its updated 399cc motor pushing out around 46 PS, is a beast. It revs high, accelerates like crazy, and feels like it’s always ready for a race. If you’re into sharp performance and lightweight flickability, this is your bike. The Guerrilla 450 has a larger 452cc Sherpa engine but is more about torque and relaxed riding. It’s perfect for cruising, pulling cleanly at low RPMs, and soaking in long rides.
Bajaj Pulsar NS400Z vs KTM Duke 390 vs Royal Enfield Guerrilla 450 Mileage Comparison
Let’s be real – if you’re buying one of these bikes, mileage might not be your top priority. Still, in India, it does matter. The Bajaj NS400Z delivers around 30-35 kmpl, which is quite decent for a 400cc bike. It balances power and economy really well.
The KTM Duke 390 is thirstier, giving about 25-28 kmpl if you’re riding sensibly. Push it hard and that number drops. The Guerrilla 450, being the heaviest and torquiest, offers 26-30 kmpl depending on your riding style. So overall, NS400Z wins the mileage round, but all three are manageable for daily use.
Bajaj Pulsar NS400Z vs KTM Duke 390 vs Royal Enfield Guerrilla 450 Features Comparison
This is where things get interesting. The NS400Z is loaded with goodies – ride modes, dual-channel ABS, slipper clutch, USD forks, and even traction control. And all this at under 2 lakh rupees! That’s crazy value. It doesn’t have a full TFT screen but the layout is clean and functional.
The Duke 390 takes tech to the next level with a bright TFT screen, smartphone connectivity, quickshifter, cornering ABS, and more. It’s the most feature-rich, no doubt. The Guerrilla 450 keeps things minimal but useful – digital cluster, LED lighting, and a USB charger. It focuses more on feel than flash.
Bajaj Pulsar NS400Z vs KTM Duke 390 vs Royal Enfield Guerrilla 450 Braking and Suspension
When it comes to ride comfort and stopping power, each bike brings a different vibe. The NS400Z gets USD front forks and a perimeter frame, giving you good high-speed stability and confident braking. It’s tuned for a nice mix of sporty handling and comfort.
The Duke 390 is the sharpest in the bunch, no doubt. Lightweight chassis, WP Apex suspension, and radially mounted brakes make it a cornering machine. The Guerrilla 450 uses a stronger frame with long-travel suspension suited for bad roads and highways. It’s more planted and plush but not built for aggressive cornering.
